Sum Yung Gai's building design is based off the real-life Chao Zhou Restaurant at 40-52 Main Street, in Flushing, Queens, which is most notable for its signature red bowl and chopstick sculpture on its roof although smaller than Sum Yung Gai's[2]; the restaurant is based in the first floor, while the second floor is occupied by a karaoke "KTV MONSTER" lounge (The "MEN STORE" sign on the building in-game is derivative of the "MONSTER" sign of the real-life karaoke lounge).

Trivia

Sum Yung Gai is a homophone of some young guy.
